SEWING-MACHINE ATTACHMENT.

Application filed October 16, 1925.

.i cloth backward and forward and from side 'to side without the necessity of stopping to lift thepresser foot at each turn of the cloth. lt will be readily seen that this device will also be of service when sewing unusually thick or soft material such! as velvet or, when lsewing a stiff material to a soft flexible material, by preventing the material from becoming ammed between the presser foot and the moving plate therebeneath.

A iinal object of this invention is the provision, in a manner as hereinafter set forth, of a darning attachment for sewing machines which will be of light but strong and durable construction, easily and quickly applied to a machine, easy to adjust and secure in the desired position, and inexpensive to manufacture.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing' of the drawing but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claim.

1n the drawing Figure 1 shows the outer face of the head of a sewing machine, showing the device embodying this invention applied thereto.

Figure 2 is a detailed perspective view of the device embodying this invention.

Referring now to the drawing in detail wherein like numerals of reference indicate corresponding parts throughout, a sewing machine head is indicated by the numeral 1, which heads of this type are as is Well known, relatively long and of rectangular Serial No. 62,804.

cross section. Extending longitudinally through the head is the presser foot bar 2 having the adjusting screw 3 upon the upper end and carrying the presser foot fi removably secured to the lower end. Extending through the back wall of the head is the usual presser foot bar lifting lever 5 which when swung upwardly acts to raise the presser foot from the work table of the machine so that material can be placed, or shifted about, therebeneath. The other parts of the machine head shown are of usual construction vand need no description.

The device embodying this invention comprises a rectangular frame or collar indicated generally by the numeral 6. This frame is formed of the parallel side bars 7 and S respectively and the cross connecting shorter end bars 9 and 10. The frame 6 is designed to it over the upper part of the head 1 as shown in Figure l and snugly engage the same on all sides, and in order to hold the frame securely in position upon the hea-d, a set screw 11 is threadably mounted in the side bar 7 and extends through the same to engage the side of the head and thus clamp the' frame securely in position thereon. f

rFhe side bar 8 of the frame is extended beyond the end of the end bar as indicated at 12, upon that side of the frame which is positioned at the back of the head 1 when the frame is in position thereon. rI his extended portion 12 is extended laterally of the frame` at right angles to the bar 8 as indicated at 13 and has extending downwardly therefrom the relatively long arm 14C which terminates at its lower end in the guide or eye 15, which eye is positioned upon the inner side of the arm. As shown in Figure 1 this arm 1li when the device is in position, is spaced from the rear wall of the head 1 and extends downwardly parallel with the face thereof.

Surrounding the arm 14 is a collar 16 having a boss 17 upon the inner face thereof and having threaded through the outer face the set screw 18 which is designed to bear against the arm 14 to hold the collar in adjusted position thereon.

Extending through the guide of the arm 14 is a relatively long bar 19 having the lower end hooked as at 2O and having the upper end extended into and secured in the boss 17 as shown.

lVhen the frame 6 is placed in position about tne head l, it Will be seen that the hook 2O of the bar 19 will be in the region of the lever 5 and this hook is designed to be engaged under the lever 5 and When the hook and lever have been drawn up to the desired position, the set screw 18 can ried by the collar 16 is tightened against the arm lll and the hook and lever thus se cured. The presser foot l- Will then be main tained at the proper height above the vvorA` table enabling the operator to move the .material being Worked upon about beneath the presser foot at Will Without the necessity of stopping to lift the lever 5 to raise the foot from the goods each time the goods is to be shifted. Darning may thus be easily and quickly accomplished With this attachment in position.

From the foregoing it will be seen that 20 an unique and serviceable attachment has been provided for sewing machines Which may easily7 and quickly be applied and set at the proper Working position Without trouble.

Having thus described my invention what l claim is A darning attachment for sewing machines having a head, a presser foot and presser foot lifting lever, comprising a frame designed to i'it about said head and be secured thereto, an arm carried by said frame, a guide carried by said arm, an adjustable collar about and carried by said arm, and a hooked rod extending through said guide and secured to said collar and designed to engage and hold said lever in set position.

In testimony whereof, I affix my signature hereto.
